AB 1240: Indoor air pollution.

(a)On or before January 1, 2024, 2025, the state board shall submit to the Legislature an addendum to the report required pursuant to Section 39930 that contains updates, as necessary based on the state boards assessment, on indoor air pollutants and their associated health impacts. The addendum shall provide updates when the science is no longer valid or is in need of further development. The state board shall consider updates, including, but not limited to, on potential health effects from ozone-emitting consumer products, natural gas sources, and indoor sources of per- and polyfluoroalkyl substances (PFAS). The addendum shall be prepared in compliance with the consultation requirement in subdivision (a) of Section 39930 and the external scientific review requirement in subdivision (c) of Section 39930.

(b)Implementation of this section is contingent upon an appropriation by the Legislature in the annual Budget Act or another statute for this purpose.

(c)The addendum described in subdivision (a) shall be submitted to the Legislature in accordance with Section 9795 of the Government Code.

(d)Pursuant to Section 10231.5 of the Government Code, this section is repealed on January 1, 2028. 2029.

(a) The state board shall, not later than January 1, 2004, 2024, in consultation with the State Department of Health Services, the Office of Environmental Health Hazard Assessment, the State Energy Resources Conservation and Development Commission, any other state agency the state board determines is appropriate, affected indoor emission sources, and interested members of the public, provide a report to the Legislature summarizing all of the following:

(1) The best scientific information available including, but not limited to, the most recent empirical data, on indoor air pollution including, but not limited to, air contaminants that have been identified as toxic air contaminants pursuant to Sections 39655, 39657, or 39660, or air contaminants for which the state board has adopted ambient air quality standards.

(2) The potential adverse effects of indoor air pollution exposure on public health in the state, including, but not limited to, vulnerable populations, including, but not limited to, elderly persons, infants, and children, based upon the information described in paragraph (1).

(3) Readily available information about the effects of existing regulations and current industry practices in mitigating those exposures.

(4) A listing that references work performed by other state or federal entities regarding biological and radiological substances, including a summary of activities conducted by the State Department of Health Services pursuant to Chapter 18 (commencing with Section 26100) of Division 20.

(b) The report described in subdivision (a) shall include all of the following:

(1) A list of indoor air pollutants that are described in the summaries provided pursuant to paragraphs (1) and (4) of subdivision (a).

(2) A list of indoor air pollutants, as defined in Section 39013, ranked in groups designated as high, medium, and lower priorities, that the state board has determined, based upon empirical data or other scientific information, are likely to have the most significant adverse impacts on human health through exposures in schools, nonindustrial workplaces, homes, and other indoor locations, and the probable source categories for these pollutants.

(3) An analysis of the indoor emissions, indoor exposures, and potential health effects from the indoor source categories described in paragraph (1), and options for mitigating those health effects in schools, nonindustrial workplaces, homes, and other indoor locations, including, but not limited to, a discussion of the feasibility and public health effects of implementing each option.

(4) A description of options for schools and school districts to improve indoor air quality in public schools. The state board shall develop these options in consultation with representatives from school district facility departments, school district maintenance departments, and statewide educational organizations.

(c) (1) The state board shall enter into an agreement with the National Academy of Sciences, the University of California, the California State University, or a similar institution of higher learning that has scientific expertise, any combination of those entities, or with a scientist or group of scientists of comparable stature and qualifications that is recommended by the President of the University of California, to conduct an external scientific peer review of the scientific basis for the report described in subdivision (a).

(2) The state board may shall not submit the report to the Legislature until all of the following conditions are met:

(A) The draft report is submitted to the external scientific peer review entity described in paragraph (1) for evaluation.

(B) The external scientific peer review entity, within the timeframe agreed upon by the state board and the external scientific peer review entity, prepares written comments that contain an evaluation of the scientific basis for the draft report. If the state board disagrees with any aspect of the findings of the external scientific peer review entity, the state board shall include as part of the final report, an explanation of its basis for arriving at that determination, including, but not limited to, the reasons that the state board determined that the report was based on sound scientific knowledge, methods, and practices.

(d) The state board shall present and review the content of the report described in subdivision (a) at a public meeting prior to before providing the report to the Legislature.
